TECHNICAL FIELD

The invention is for compositions and method for using said compositionsto improve the performance of long-wearing cosmetic products. Thesecompositions and methods for using such compositions enable the user tosignificantly enhance the attributes of long-wearing cosmetic productswithout compromising their primary advantages.

BACKGROUND ART

Compositions used to enhance cosmetic products are known in the art.Such compositions include those that are applied over top compositionssuch as lipstick to provide attributes such as gloss, lubricity andtransfer-resistance of the cosmetic product they are applied over. Theseenhancement products utilize a variety of polymeric fluids and filmforming technologies. For example, acrylic film-formers that areincorporated in lipstick overcoat products such as CSI Incorporated's“Sealed with a Kiss” are delivered in a volatile vehicle, alcohol, whichis spread over the lipstick surface.

Alternative topcoat products to those described above are disclosed inJapanese Patent Application Number HEI 5[1993]221829, published Aug. 31,1993. Said overcoats are reputed to exhibit improved durability ofmakeup effect, suppression of color transfer, and improvedapplicability. Said topcoats comprise from 0.2 to 25% of silica powderand/or alumina powder and from 75% to 99.8% of a perfluoropolyether ofgeneral formula:

wherein R¹ though R⁵ are independent fluorine atoms, perfluoroalkylgroups, or oxyperfluoroalkyl groups; the value of p, q, and r is atleast zero; wherein the perfluoropolyether molecular weight is fromabout 500 to about 10,000, wherein P, Q and R may be equal, but, notzero. The preferred perfluoropolyether disclosed therein is acommercially available product known as Fomblin HC-04, HC-25, and HC-Ravailable from Montefluosu of Milano, Italy.

While such compositions may provide certain advantages, it has beenfound that they often disrupt the primary advantages of the cosmeticproducts they are applied over. For example, cosmetic productscompromise their gloss or feel attributes in order to improve the longwear properties provided by the composition that is applied over top thecosmetic product. Alternately, cosmetic products must sacrifice longwear properties in order to improve the gloss and or feel attributesprovided by the such compositions.

SUMMARY OF THE INVENTION

The present invention is for compositions and methods for using saidcompositions with cosmetic products having a solubility parameter lessthan or equal to 8.5 (calories/cm³)^(½) in order to improve the overallperformance associated with the cosmetic product. These compositionscomprise oils having a C log P value greater than or equal to 13.

Additionally, the present invention covers a method of improvingtransfer resistant, flexible film-forming cosmetic product wherein saidmethod comprises the steps of:

a. applying a transfer resistant, flexible film-forming cosmetic productwherein said cosmetic product has a solubility parameter less than orequal to 8.5 (calories/cm³)^(½);

b. allowing said cosmetic product to dry; and

c. applying over said cosmetic product a second composition wherein saidsecond composition comprises an oil having a C log P value greater thanor equal to 13.

BACKGROUND OF THE INVENTION

When supplementing the benefits of a cosmetic product, the complimentingor second composition should minimize compromising said cosmeticproduct. The compositions of the present application may be used inconjunction with all types of cosmetic products wherein it is desirableto provide additional attributes. In the case of lip products, suchattributes include gloss, shine and lubricity.

Specifically in context of film-forming cosmetic products, the secondcomposition should be incompatible with the cosmetic product. Byincompatible it is meant that the compositions of the present inventioncomprise specific components that do not disrupt the film formed afterapplication of said cosmetic product. This is particularly the case fortransfer-resistant, flexible film-forming cosmetic products such as lipcosmetics.

Lip cosmetics are well known in the art and can encompass a number ofdifferent formulations in order to provide both cosmetic and skin carebenefits to the skin. One benefit that has been most often sought byconsumers, particularly in lip cosmetic product, is increased or “long”wear.

Long wearing cosmetic products are considered by some to be those thatare resistant to blotting on to another object that comes in contactwith the cosmetic product; for example, resistance to lip compositioncoming off onto table wear such as cups and napkins. However, otherfactors found to be critical in predicting long wear is the ability ofthe cosmetic product to be flexible and resistant to solvents such asfood oils once applied to the skin. Such cosmetic products are thesubject matter of co-pending patent applications USSN 08/732,946 andUSSN 08/732,948, now U.S. Pat. No. 6,071,503. “Transfer ResistantCosmetic Compositions”, Drechsler et al., both filed Oct. 17, 1996; bothincorporated herein by reference. Such compositions compriseorganosiloxane resins, fluid diorgansiloxane polymers, and a volatilecarrier wherein the film formed upon application of the cosmetic productis substantially transfer-resistant and flexible wherein the cosmeticproduct has surprisingly increased wear.

In one embodiment, such cosmetic compositions comprise (A) a mixture of(1) an organosiloxane resin and (2) a fluid diorganopolysiloxanepolymer, wherein the ratio of (1) to (2) is from about 1:1 to about 20:1when (2) has a viscosity from about 1,000 to about 200,000 cSt at 25°C., and a ratio of (1) to (2) from about 1:9 to about 20:1 when (2) hasa viscosity greater than 200,000 cSt at 25° C.; and (B) a volatilecarrier.

The cosmetic products used in conjunction with the composition of thepresent invention have solubility parameters less than or equal to about8.5 (calories/cm³)^(½) on the Hildebrand scale. In general, thesolubility parameter is a function of the cohesive energy of thematerials or the cosmetic product comprising said materials. Cohesiveenergy is simply an attractive force that is dependent on theelectro-negativities of the atoms making up a molecule and serves as thebasis for properties such as viscosity, adhesion, miscibility and eventhe boiling point. Some materials, like water, have high cohesiveenergy; some, like oil, have low cohesive energy. Highly cohesiveingredients are “polar”, while those less cohesive are oily or“non-polar”. Hildebrand developed a method for deriving the solubilityparameter from the boiling point, molecular weight and specific gravityof a material; J. H. Hildebrand, J. M. Prausnitz and R. L. Scott,Regular and Related Solutions, New York; Van Nostrand Reinholdt (1950),herein incorporated by reference. This Hildebrand solubility parameteris published for many cosmetic and pharmaceutical materials in theCosmetic Bench Reference, Carol Stream Ill., Allured Publishing (1992)and in A. F. Barton, Handbook of Solubility Parameters and OtherCohesion Parameters, 2nd ed., Boca Raton; CRC Press (1992); bothincorporated herein by reference.

The C log P value of the oils in said composition determines whether thecomposition of the present invention is sufficiently incompatible withthe cosmetic product in order to improve the cosmetic productsperformance. The value P is the octanol/water partitioning coefficientof the oils comprising said composition. The octanol/water partitioningcoefficient is the ratio between said compositions equilibriumconcentration in octanol and in water. Since the values of theoctanol/water partitioning coefficient are high, they are moreconveniently given in the form of the logarithm to the base 10, or logP.

The log P values above are calculated using the “C log P” programavailable from Daylight CIS. This calculated logarithm of P is based onthe fragment approach of Hansch and Leo (cf., A. Leo, in ComprehensiveMedicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor andC. A. Ransden, Eds., p. 295, Pergamon Press, 1990); incorporated hereinby reference. The fragment approach is based on the chemical structureof each oil ingredient, and takes into account the numbers and types ofatoms, the atom conductivity, and chemical bonding. The C log P valuesare the most reliable and widely used estimates for this physiochemicalproperty.

Compositions of the present invention comprise oils and may take formsranging from solid to liquids. Regardless of the form, compositions ofthe present invention contains at lest one oil wherein the aggregate Clog P value for all the non-solid molecular entities is about that ofthe oil alone. The C log P value of the oils in said composition aregreater than or equal to 13, preferably greater than or equal to 17, andmost preferably greater than or equal to 20. The oils used in thepresent invention are selected from the group consisting of polyol fattyacid polyester, triglycerides, fluid synthetic polymers and mixturesthereof.

a. Solid Polyol Polyesters

The solid polyol polyesters used in the present invention are polyolesters or polyesters wherein the fatty acid ester groups of thepolyester comprise a combination of: (a) long chain unsaturated fattyacid moieties or a mixture of long chain unsaturated fatty acid moietiesand short chain saturated fatty acid moieties, and (b) long chainsaturated fatty acid moieties, the ratio of (a) to (b) being from about1 to 15 to about 2 to 1. At least about 15%, preferably at least about30%, more preferably at least about 50%, and most preferably at leastabout 60% by weight of the total fatty acid moieties of the polyestersare C20 or higher saturated fatty acid moieties. The long chainunsaturated fatty acid moieties are typically straight chain and containat least about 12, preferably about 12 to about 22, more preferablyabout 18 to about 22 carbon atoms. The most preferred unsaturated fattyacids are the C18 mono and/or di unsaturated fatty acids. The shortchain saturated fatty acids are typically unbranched and contain about 2to about 12, preferably about 6 to about 12, and most preferably about 8to about 12 carbon atoms. The long chain saturated fatty acids aretypically straight chain and contain at least about 20, preferably about20 to about 22, and most preferably about 22 carbon atoms. The molarratio of Group (a) fatty acid moieties to Group (b) fatty acid moietiesin the polyester molecule is from about 1:15 to about 2:1, preferablyabout 1:7 to about 5:3, and more preferably about 1:7 to about 3:5. Theaverage degree of esterification of these fatty acid esters is such thatat least about 60% of the hydroxyl groups of the polyol are esterified.In the case of sucrose polyesters from about 7 to about 8 of thehydroxyl groups of the polyol are preferably esterified. Typically,substantially all, e.g., at least about 85%, preferably at least about95%, of the hydroxyl groups of the polyol are esterified. Preferredpolyols of the solid polyol fatty acid esters are sugars selected fromthe group consisting of monosaccharides and disaccharides andtrisaccharides, comprising from about 4 to about 11, preferably about 4to about 8 and most preferably about 6 to about 8 hydroxyl groups.Examples of those containing four hydroxyl groups are themonosaccharides xylose, arabinose, and combinations thereof. Suitablefive hydroxyl group-containing polyols are the monosaccharidesgalactose, fructose, mannose, glucose, and combinations thereof.Examples of disaccharide polyols which can be used include maltose,lactose, sucrose, and combinations thereof, all of which contain eighthydroxyl groups. The preferred polyol is sucrose.

Examples of long chain unsaturated fatty acid moieties include, but arenot limited to, lauroleate, myristoleate, palmitoleate, oleate,elaidate, erucate, linoleate, linolenate, arachidonate,eicosapentaentoate, and docosahexaenoate. For oxidative stability, themono- and diunsaturated fatty acid moieties are preferred.

Examples of suitable short chain saturated fatty acid moieties include,but are not limited to, acetate, caproate, caprylate, caprate, andlaurate.

Examples of suitable long chain saturated fatty acid moieties include,but are not limited to, arachidate, behenate, lignocerate, and cerotate.

Of course, the long chain unsaturated fatty acid moieties can be usedsingly or in mixtures with each other or in mixtures with the shortchain saturated fatty acid moieties, in all proportions. Likewise, thelong chain saturated fatty acid moieties can be used in combination witheach other in all proportions. Mixed fatty acid moieties from sourceoils which contain substantial amounts of the desired unsaturated orsaturated acids can be used as the acid moieties to prepare compoundsfor use herein. The mixed fatty acids from the oils should contain atleast about 30%, preferably at least about 50%, and most preferably atleast about 80% of the desired unsaturated or saturated acids. Forexample, rapeseed oil fatty acids or soybean oil fatty acids can be usedinstead of pure C12-C16 unsaturated fatty acids. Hardened, i.e.hydrogenated, high erucic rapeseed oil fatty acids can be used insteadof pure C20-C22 saturated acids, Preferably the C20 and higher acids, ortheir derivatives, e.g. methyl or other low alkyl esters, areconcentrated for example by distillation. The fatty acids from palmkernal oil or coconut oil can be used as a source of C8 to C12 acids, Anexample of the use of source oils to make solid polyol polyesters foruse in the compositions herein is the preparation of solid sucrosepolyester, employing the fatty acids of high oleic sunflower oil andsubstantially completely hydrogenated high erucic rapeseed oil. Whensucrose is substantially completely esterified with a 1:3 by weightblend of the methyl esters of the fatty acids of these two oils, theresulting sucrose polyester will have a molar ratio of unsaturated C18acid radicals to C20 and higher saturated acid radicals of about 1:1 andabout 28.6 weight percent of the total fatty acids in the polyester willbe C22 fatty acids.

The higher the proportions of the desired unsaturated and saturatedacids in the fatty acid stocks used in making the solid polyolpolyester, the more efficient the ester will be in its ability to bindwith the liquid oils described hereinbelow.

Examples of solid polyol fatty acid polyesters for use in thecomposition herein include, but are not limited to, the octaester ofraffinose in which the esterifying fatty acid moieties are linoleate andbehenate in a 1:3 molar ratio; the heptaester of maltose wherein theesterifying fatty acid moieties are sunflower seed oil fatty acids andlignocerate in a 3:4 molar ratio; the octaester of sucrose wherein theesterifying fatty acid moieties are oleate and behenate in a 2:6 molarratio; and the octaester of sucrose wherein the esterfying fatty acidmoieties are laurate, linoleate and behenate in a 1:3:4 molar ratio. Apreferred material is sucrose polyester in which the degree ofesterification is 7-8, and in which the fatty acid moieties are C18mono- and/or di-unsaturated and behenic, in a molar ratio ofunsaturates:behenic of 1:7 to 3:5. A particularly preferred polyol esteris the octaester of sucrose in which there are about 7 behenic fattyacid moieties and about 1 oleic moiety in the molecule.

The solid fatty acid polyesters herein can be made according to priorart known methods for preparing polyesters of polyols. See, for exampleU.S. Pat.
